Cushioning properties of moulded pulp
Packaging Technology and Science, 1994AbstractCushion curves for a moulded pulp material were constructed and compared with cushion curves for an expanded polystyrene (EPS) foam. The ability of the moulded pulp material to provide some shock absorption resulted from a number of ‘dimples’ moulded into the pulp sheet.

Properties of hyperalkaline polysulphide pulps
Nordic Pulp & Paper Research Journal, 1997The term hyperalkaline polysulphide pulping is used to denote a process utilising a polysulphide pretreatment step at high alkalinity. The stabilising effect of polysulphide on carbohydrates is enhanced by higher alkali concentrations. The high alkali concentration in the stabilisation stage also increases the delignification rate in the subsequent ...

Rheological Properties of Butia Pulp
International Journal of Food Engineering, 2006Rheological parameters of Butia pulp were determined at different temperatures using a concentric cylinder Haake Rotovisco rheometer, model RV-20, with measurement system ZA-30. Butia pulp was found to exhibit non-Newtonian, pseudoplastic behavior at all temperatures and the rheological parameters were adequately described by the Herschel-Bulkley model.

Properties of Alkaline Phosphatase of the Human Dental Pulp
Journal of Dental Research, 1990Enzymatic and immunological properties of alkaline phosphatase [ALP; orthophosphoric monoester phosphohydrolase, alkaline optimum, EC 3.1.3.1.] in the human dental pulp were investigated. In inhibition and thermal inactivation studies, dental pulp ALP showed properties of universal-type ALP (kidney/bone/liver type).

Cellulose, 1999
The mechanical, physical, and chemical properties of recycled pulps were evaluated after a series of treatments designed to improve and/or modify the pulp characteristics. Tensile strength, bursting strength, and apparent density of the pulps decreased with recycling. However, the tear strength, in most cases, increased after the first recycle and then

PEROXIDE PULPING PROPERTIES OF ANNUAL PLANTS. 5. DEFORMATION PROPERTIES OF PULP SHEET
2013Пероксидная целлюлоза (получена делигнификацией реакционной смесью «Н2О2–Н2О–АсОН–АсООН–катализатор») и сульфатная целлюлоза из стеблей пшеничной соломы размолоты до 28–30о ШР. Определены деформационные свойства бумажных отливок: модуль упругости, работа деформации, жесткость и продолжительность релаксации при растяжении и др.
